So I just did a little experiment blocking my bank card RFID capabilities.
I used some ferrite polymer sheet first and it attenuated the signal and made it harder to read with just a 1mm sheet between the card and scanner.
then I tried the card wrapped both sides and it blocked the RFID 90% of the time.
then I tried some foil wrap used commonly in electronic cables etc. which was far more effective and proved impossible to read the RFID tag.
so is this multi million dollar market for RFID blocking wallets etc just an exploitative method of getting the security conscious and technophobic sector of the community to part with premium cash for a not so premium solution?
your thoughts please... tinfoil hat optional
